LocK-HlNce;

SPECIFICATION forming part of Letters Patent No. 521,429, dated J' une 12, 1894. Application filed August 4, 1893. SerialNo.482,355. (No model.)

To a/Z whom/.it may concern: v

Be it known that LWILLIAM T. BEssoNETTE, a citizen of the United States, residing at Temple, in the county of Bell and Stateof Texas, have invented a new anduseful Combined Door Hinge and Lock, of which the following is a specification.' 1

My invention relates to a combined door hinge and lock, and has for its object to provide, in combination with the hinge of an ordinary general construction, aldevice whereby the door is automatically locked or held in aset position without special adjustment or manipulation, and by which, by the adjustment of a member provided for that purpose, the-door may be locked permanently in any` desired position.

The 'invention is designed. especially for use in connection with house and railway pasparticularly senger coach doors, shutters, gates, dac., and

may be applied effectively tofscreen doors and the like. 'l v Further objects and advantages of my invention will appear in theollowing description, and the novel features thereof will be pointed out in the appended claims. j

In the drawings: Figure l is a front View of a hinge embodying my invention. v Fig. 2

is a sectional View parallel with the plane of `Fig. l. Fig.3 is a detail view in perspective,'

showing the parts-of the hinge disassembled.

Similar numerals of reference indicate corresponding parts in all the iigures of the drawlngs. y J

1 and 2l represent,- respectively, the leaves of the hinge, theleaf l being provided with a single tubular eye 8, whichl is arranged between andjin registration with the tubular eyes 4 and 5 .of the leaf 2. The eye 5, which is preferably slightly larger in diameter than the eye 4, is extended beyond the terminal of the leaf to which it is attached, and fitting in its inner end is a slidable plunger 6.' This plunger and the contiguous end of the eye 3,

between which and the end of the eye 5 such plunger is arranged, are provided respectively with the co-operating members 7 and 8 of a clutch, such clutch-members being provided with intermeshing ratchet faces having beveled teeth whereby they may slide upon each other as the door is swung to and fro. The clutch-member 8 is provided with a bifurcated guiding lug 9, which engages the inner edge'of the leaf 2 to prevent independent rotary movement of the said member, and the stem of the plunger carrying said clutch-member is tubular and registers with the eyes 3 and 4. :The slidable clutch-'member is springactuated, the outer end of the plunger-stem being engaged by an actuating coiled spring v 10, which is disposed within the extended eye 5 and is held in operative relation to the plunger by means of an adj usting-screw 11, bearing upon its free or outer end, and threaded inthe bore of the eye. This adjustingscrew is provided with a milled headv 12, to facilitate adjustment.

14 represents the pivot-pin of the hinge, which extends through the registering eyes 3, 4, and 5, and also `through the bore of `the plunger, and it is preferably formed integralmay be regulated by means of the adjustingscrew. When the tension kof said springV is ,adjusted -toV permit` of the free movement of the door, the slidable clutch-member is, by the ojo-action of the ratchet-faces, repressed as the door is moved, such clutch-member being returned by its actuating spring as the teeth of the two members come into alignment. Thus, when the door comes to rest the teeth of the clutch-members are in engagement and the door is temporarily locked or held from vibration bythe wind or ordinary jar. If, however, it is req'uired `to lock the door permanently, the adj usting-screw is manipulated to increase the tension of the actuating spring, thus locking the teeth of the clutch-members in engagement and preventing the movement of the door.

Various changes in ther form, proportion,

IOO

and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having described the invention, what I claim isl. The combination with ahinge, of a clutch having one of its members secured to and carried by one of the leaves of the hinge, and the other of its members sldably mounted upon the other leaf of the hinge with its face in operative relation with the firstnamed member, a spring arranged to actuate the slidable member and hold the same in engagement with the fixed member, and an adjusting-screw operatively connected to the spring to vary the tension thereof, substantially as specified.

2. The combination with a hinge having its leaves connected by a pivot-pin, of a clutch having one of its members fixed to one of the leaves and its other member slidably mounted upon the other leaf, in registration with the eyes forming parts of said leaves, an actuating-spring arranged in operative relationv WILLIAM T. BESSONETTE.
